Panel Indicators, Pilot Lights are main signaling logos or indicators used on the control panel mainly to determine the running status, operation conditions, and operation mode of industrial control instruments or machines. 5102H1-5V (hereafter referred to as “the instrument”) is a typical display instrument developed by Beijing HYC based on the traditional design. In this passage, its application field and working principle will be provided.

Application Field

Panel Indicators, Pilot Lights are widely used in various control panels related to various industrial control instruments or machines, such as electric motors, potentiometer, controllers, and switch amplifier. In addition, it can also be used in various remote control systems. The instrument is especially designed to be applied in petroleum, chemical, metallurgic industry, which requires caution about the flames’ shutoff and pneumatic. It can be conveniently used in densely populated locations where mechanical operation is not a viable option.

Working Principle

The instrument makes use of bulb or LED as the power switch that lights up when the system is on and goes out when the system is off. It is usually connected with the positive terminal of the power supply and the other side is connected to the line instructed by the instrument.

The function of the instrument is achieved mainly by the connection between the components. A negative contact of the electronic switch is connected to the bulb, the positive contact of the electronic switch is connected to the line instructed by the instrument. When the system is off, the negative contact of the electronic switch is not turned off and the bulb will not lit up.

When the sensor detects an abnormality such as higher or lower temperature, then the electronic switch will open. At this time, the positive contact of the electronic switch is connected with the line instructed by the instrument, and then the bulb will lit up. Since the setting time is preset and the lamp will switch off automatically after the set time passes. This principle can help the detection of abnormality in systems.

Apart from the traditional function mentioned above, the instrument also has some technical improvements. The instrument has a built-in amplifier, which can effectively control the impedance of the detector, thus improving the operation performance of the instrument. Furthermore, the instrument also adopts the over-temperature protection system which means discontinuing of the power supply when the temperature exceeds a certain value.

In conclusion, the instrument can work more efficiently with higher accuracy in controlling the temperature difference and pneumatic under different working conditions. It is fully capable of performing all the tasks as expected, and this useful tool can enhance the work efficiency and safety in a variety of applications.
